Maintenance and care
Use of a non-approved automatic transmission fluid may cause
internal transaxle component damage.
If necessary, add fluid in 250 mL (1/2 pint) increments through the filler
tube until the level is correct.
If an overfill occurs, excess fluid
should be removed by a qualified
technician. DON'T ADD IF IN CROSSHATCH AREA--CHECH WHEN HOT-IDLING
An overfill condition of
transmission fluid may cause shift and/or engagement concerns
and/or possible damage.
CABIN AIR FILTER (IF EQUIPPED)
The cabin air filter restricts the entry of airborne dust and pollen
particles. The filter is located just in front of the windshield under the
cowl vent screen on the passenger side of the vehicle.
